Configuration

Continuing with the example configuration:

1. Expand the Conditioning Orifice Plate category.

Figure 3-10. Primary element selection tab - 405C/3051SFC

2. Select 405C/3051SFC.

3. Enter the Measured Meter Tube Diameter (pipe ID) at a Reference Temperature. If the meter

tube diameter cannot be measured, select a Nominal Pipe Size and Pipe Schedule to input

an estimated value for the meter tube diameter (U.S. units only).

4. If necessary, edit the Meter Tube Material.

5. Enter the Line Size and select the Beta of the Conditioning Orifice Plate. The required

primary element sizing parameters will be different depending on what primary

element is selected.

6. If necessary, select a Primary Element Material from the drop-down menu.

7. A calibration factor may be entered if a calibrated primary element is being used.

Note

A Joule-Thomson Coefficient can be enabled to compensate for the difference in process

temperature between the orifice plate location and the process temperature measurement

point. The Joule-Thomson Coefficient is available with ASME MFC-3M-2 (2004) or ISO

5167-2.2003 (E) orifice plates used with Database Gases, Superheated Steam, or AGA DCM/ISO

Molar Composition Natural Gas. For more information on the Joule-Thomson Coefficient, please

reference the appropriate orifice plate standard.
